How do I establish VPN when I TURN COMPUTER ON and BEFORE I log in as one of 3 users?

I wrote a batch file and placed it in Startup Folder to establish a VPN connection. It works but only when I log in as a user. I want the connection established when the computer turns on , without having to log in as a user.|||What type of VPN? Many commercial clients such as Cisco have a setting that does just that. If you're trying to do it with the Microsoft vpn connection, you'll have to set it up as a service.
